Working with xref's that were created in microstation(the xref's have been converted to dwg.s by the engineering comp. that created them).....If I try to plot any of these backgrounds it somehow kicks out my custom Plot style tables....The only options I have to plot from is none, acad.stb,and mono.stb....these existing plotstyles....(I guess from thier xref's) will not even let me manipulate them to do what I need to do...any advice is appreciated...This is my first experience with microstation entities....
